Kick the Addiction, Save Money

The political case for the War on Drugs has always been intuitive. “Drugs are bad” has trumped practical concerns. But the actual, responsible case for the political crusade has depended upon some concept of “social cost.”

Now that marijuana is being legalized state by state, the case against the greater War on Drugs is being taken seriously — enough to rethink all varieties of costs. Indeed, many now seethe opioid epidemic as being driven, in part, by the War on Drugs, and not just as an excuse for a stronger crackdown.

Nevertheless, coming to some accounting — especially “social cost” accounting — remains difficult. This is especially true so long as its effects on freedom and the rule of law do not get figured in.

Somewhat surprisingly, even the budgetary effects of legalization have proven a bit tricky.

So it is welcome to read Harvard economist Jeffrey Miron’s study of marijuana legalization as it has occurred in the states of Washington, Oregon, and Colorado. He compares results of legalization with the predictions he had made eight years ago, in a previous Cato Institute study. It turns out that while tax revenues are far greater than expected, law enforcement costs have not gone down.

“Early experience suggests that governments will reallocate rather than reduce those expenditures,” Miron writes. “That reallocation may be beneficial, but it does not have a direct effect on the budget deficit.”

On a federal level, though, we might expect greater savings. How? We could shut down whole bureaus.
